Y^3(Y^3-Y)=???

We know Y=3 so this, Y^3(Y^3-Y) now looks like this..

3^3(3^3-3)

For the outside

we know 3^3=27

Ex. 3x3x3=27

Break Down

3x3=9x3=27

So from Y^3(Y^3-Y)

we went to 3^3(3^3-3)

to this 27(27-3)

Now subtract 27-3=24to get you final X

27(24)= or 27*24= 648

Steps...

Y^3(Y^3-Y)

Y^3(Y^3-Y)

3^3(3^3-3)

27(27-3)

27(24)= or 27*24= 648

When y itself is negative, -y becomes positive.

Suppose y is -3.

Then -y is -(-3) which is +3. Got it? Hope so.
